Phys.org / From the lab to the moon: Lunar cement alternative survives 6 months on ISS and returned stronger in some tests
Building material samples from the University of Delaware spent six months mounted outside the International Space Station, where the harsh conditions of low Earth orbit tested their limits.
Phys.org / JWST finds the most distant barred galaxy candidate in the early universe
Astronomers using the James Webb Space Telescope have identified what may be the most distant barred spiral galaxy ever discovered, dating to a time less than 1.2 billion years after the Big Bang. The paper outlining its ...
Phys.org / Q&A: Examining the Global South's call for environmental justice amid expanding technology
Digital technologies—from artificial intelligence to smartphones and data centers—are often described as "clean" innovations. Yet every device depends on minerals, electricity, labor and global supply chains, raising important ...
Phys.org / Much of Earth's 'space dust' may come from unidentified near-Earth asteroids
Like a shelf in an old house, the Earth collects a lot of dust from its surroundings. This "space dust" is mostly made up of micrometeorites that survive atmospheric entry and provides researchers with a cheap and easy way ...
Medical Xpress / Most obesity drugs do not improve quality of life or heart health, analysis indicates
Despite substantial weight loss, most obesity drugs such as Wegovy and Mounjaro do not meaningfully improve quality of life, and few show cardiovascular benefits at one year, according to an analysis of the latest evidence ...
Phys.org / What to know about the total solar eclipse due in August
Day will briefly turn into night across a swath of northern Spain on Aug. 12, when the moon will completely cover the sun during a rare total solar eclipse.
Medical Xpress / Higher blood glucose levels linked to faster brain aging
The human brain is known to naturally change with age, shrinking in size and volume after people reach their 30s or 40s. In some cases, however, it can age faster than expected, which can increase the risk of early memory ...
Phys.org / Scientists just measured the smallest possible contacts for future computer chips
The rise of AI has created an almost insatiable appetite for computing power. Training and running AI systems requires vast numbers of transistors, and engineers are now racing to pack more of them onto every chip. With their ...
Phys.org / Strengthening El Nino likely to 'rank among largest' on record
The El Nino weather pattern picked up strength over the past month and is highly likely to "rank among the largest" ever recorded when it peaks between October and December, U.S. forecasters said Thursday.
Tech Xplore / Researchers develop a new way to build molecular 'ladders' for organic electronics
Ladder-type oligothiophenes are an important class of sulfur-containing π-conjugated molecules. Because their fused, ladder-like structures can support efficient electronic interactions, they are widely studied as core motifs ...
Phys.org / Baseline tool could separate alien life signals from geology on ocean worlds
When it comes to the search for life elsewhere in the universe, methane and other chemical compounds are seen as signs of biology because they are often produced by living microbes. However, scientists can be misled because ...
Phys.org / 'Cosmic wallflowers' may hold the key to the origin of globular clusters
Astronomers using computer simulations have investigated whether a class of star clusters nicknamed "cosmic wallflowers" could be the long-sought ancestors of the globular clusters we see orbiting galaxies today. Their paper, ...
